Wanted to do a particle count on the Purolator BOSS PBL14476 filter. Just to see how it filters. Took a sample at 500 miles. The next one will be when the filter has 8,500 miles on it using HPL Premium Plus 5W-20. Seems to do a decent job.

Thanks for UOA and particle count testing. It’s not too often that people get this done, but I’m wondering about your comment that that filter is doing a good job… @ZeeOSix can you confirm? Based on this page from Donaldson, it appears you’ve got somewhere between 4 million and 8 million particles per 100mL if I’m reading this table correctly… like I said I may be off but generally speaking the Boss is not considered premium filtration.

It doesn't look bad, but it only has 500 miles on the oil. You could put new oil in an engine and run it 500 miles with just a screen for an oil filter and probably have a PC that doesn't look too bad. Like I've mentioned in other threads about PC data, to get a real apples-to-apples comparison of in field filter performance using an ISO 4406 particle count, the filters need to ideally be ran on the same engine and basically used in the same conditions for the same OCI. As the miles get put on the oil more debris is generated, and the lower micron size levels should start increasing because filters are less efficient at capturing the smaller stuff, and less efficient filters may also slough off debris with loading dP - a more inefficient filter will show that. This all points back to the reasons to use a high efficiency oil filter for longer OCIs. PS - Yes, the ISO 4406 particle count is the number of particles per mL of oil.
Thanks for testing at 500. I'll patiently wait for your 8500 mile results w/HPL 5w-20.
What you using HPL oil in Justin?
OP: thanks for doing this. Good info
Thanks. Like I said, it’s been awhile since we discussed particle counts. Didn’t want to jump off the deep end without a refresher from somebody more knowledgeable.
I’d love to see this done with say the Boss and one of the microglass Donaldson’s, and against the Endurance as well.
Nice! The next particle count will tell more. Just understand that because it’s a purolator no matter how great it might preform, around here it will be minimized and or overlooked.
Particle count data without a controlled comparison test to other filters is pretty useless if trying to rank their in use filtering performance. You won't really get any meaningful comparison data if not conducted like described in post 6.

I'm gonna do some particle analysis with different filters running to 10k with the HPL oil stash.
Whats on the list of filters I plan running with magnetic assisted filtration using N42SH bars and SmCo disc, keep in mind these are oversize from the OEM size which is the YZZN1 / Fram 4967
P551132
FE3600
FS3600
LF16011
MSL51516
I'm not sure if I want to run a PBL20195 to 10k though I wait for OP results as I do care a lot to keep my daily in top condition.
Although you’re not going to get an accurate representation of the filter by using the magnets. If you want to get the best data, you’d run almost your full OCI on filter alone & pull sample. Then add magnets and pull another sample 500 miles later. That way you can separate the effect of the magnets vs the filter itself. You may well find that the magnets are more effective on some filters than others… I’d bet the less-efficient filters would end up with more on the magnet, but that’s a WAG at this point.
Well to be honest nothing at the moment. Stocked up on that $25 5w-40 Mobil Euro Walmart glitch.
Plus about x2 Mobil Delvac 15w40 in 5 gallon buckets. Think you've run some HPL right?Well to be honest nothing at the moment. Stocked up on that $25 5w-40 Mobil Euro Walmart glitch.
YUP! No VII 5w20 and currently 50% CK-4 5w20 HDEO HPL and DELVAC 1 ESP 5w40 in the daily driver 09’ Focis.
It took almost 3 weeks
I've got 14 different Blackstone particle counts from 5 different engines I've saved from this site. Yours would be tied with a WIX (Non-XP) for last place, and just ahead of worse than a 40-micron Baldwin filter.
Different engines will produce different results with the same filter, but unless your engine has a problem, it's safe to say that this Purolator BOSS has poor efficiency. For reference, 6 different particle counts with PurolatorOne filters on three different makes/models of engine were all in the range of ISO 14/13/11 to ISO 17/16/14.

3 weeks is a very long time, WearCheck only took 2 days from the day it arrived to their lab.
Thanks for sharing. The BlackStone pricing looks decent since its 25 dollars just for the particle count only.
Curious to see how this filter holds up at 10K on your run. Keep is updated and thanks.
Using the magnets could skew the actual performance of the filter to some degree, especially if a pretty inefficient filter is ran. A high efficiency filter that can capture a good percentage of 5u particles would probably show better performance than an inefficient filter without magnets in the mix.

Yeah I agreed with Subie's reply about that earlier, that being said. It would be backwards for me to remove those magnets including the magnetic drain plug to run a more controlled run. There are 4 samarium cobalt disc currently on the baseplate of the P551132 filter I'm running for the past 4K miles. Before that I already had N42SH bars on the previously pulled FS3600.
I guess I can do a more controlled run with another vehicle in the future but my daily gets the drop treatment and care haha.
